It is almost 3:30 am now, I stayed awake for last 23 hours so that Excel School 2 can be ready for rolling. But that is no excuse for not having a post here. So here it goes.
Excel has formulas for converting a bunch of text to UPPER, lower and Proper Cases. But not a formula to convert o Sentence case. So, today we will learn a simple formula tip to convert text to sentence case (ie, First letter capital).
Assuming your text is in C2, the formula is,
=UPPER(LEFT(C2,1))&MID(LOWER(C2),2,999)
How the formula works?
It is converting first letter of C2 to upper case [UPPER(LEFT(C2,1))] and lower case of rest of C2 [MID(LOWER(C2),2,999)]
The 999 portion is the secret code to unlock ninja features of MID formula.
Well, I am kidding of course, the 999 is just a cop-out to say give me rest of the C2, I don’t know the length of it. (of course, 999 would fail if your text actually has more than 1000 chars. In that case, just use 9999 or whatever large number you fancy.)
Another formula:
=SUBSTITUTE(LOWER(C2),CHAR(CODE(C2)),UPPER(CHAR(CODE(C2))),1)
PS: As you can guess, the above formulas assume that C2 has one sentence. If C2 has a whole paragraph, then I would really need a sandwich before thinking about that problem.

Do you have links to any sites that can provide free, large, test data sets. Both large in diversity and large in total number of rows.
Good question Ron. I suggest checking out kaggle.com, data.world or create your own with randbetween(). You can also get a complex business data-set from Microsoft Power BI website. It is contoso retail data.
Hi Chandoo,
I work with large data sets all the time (80-200MB files with 100Ks of rows and 20-40 columns) and I've taken a few steps to reduce the size (20-60MB) so they can better shared and work more quickly. These steps include: creating custom calculations in the pivot instead of having additional data columns, deleting the data tab and saving as an xlsb. I've even tried indexmatch instead of vlookup--although I'm not sure that saved much. Are there any other tricks to further reduce the file size? thanks, Steve
Hi Steve,
Good tips on how to reduce the file size and / or process time. Another thing I would definitely try is to use Data Model to load the data rather than keep it in the file. You would be,
1. connect to source data file thru Power Query
2. filter away any columns / rows that are not needed
3. load the data to model
4. make pivots from it
This would reduce the file size while providing all the answers you need.
Give it a try. See this video for some help - https://www.youtube.com/watch?v=5u7bpysO3FQ
Normally when Excel processes data it utilizes all four cores on a processor. Is it true that Excel reduces to only using two cores When calculating tables? Same issue if there were two cores present, it would reduce to one in a table?
I ask because, I have personally noticed when i use tables the data is much slower than if I would have filtered it. I like tables for obvious reasons when working with datasets. Is this true.
John:
I don't know if it is true that Excel Table processing only uses 2 threads/cores, but it is entirely possible. The program has to be enabled to handle multiple parallel threads. Excel Lists/Tables were added long ago, at a time when 2 processes was a reasonable upper limit. And, it could be that there simply is no way to program table processing to use more than 2 threads at a time...
When I've got a large data set, I will set my Excel priority to High thru Task Manager to allow it to use more available processing. Never use RealTime priority or you're completely locked up until Excel finishes.
That is a good tip Jen...
